Lifting to high tops, breaking up
A deck of cloud covers high Cairngorms early in day, bases lowest around Drumochter/west of A9, some low ragged patches in sheltered areas. Soon lifting, to just banks rolling over the Cairngorm plateau, these increasingly breaking up. Clearer east.
Gradually rising to 60%, 90% east.

Chance of a brief light shower.
Varied patches likely all clearing

Changeable west-southwesterlies prevail through mid September; often windy, gale-force winds for periods over higher terrain. An active frontal system sweeps southeastward on Saturday with a sustained fall of rain, accompanied by upland gales for most places. Improving for better weather on Sunday, then wind and rain returns into Monday, staying showery into Tuesday. A mixed outlook likely continues later next week with rain most frequent in western Scotland. Temperatures varying, some cooler days especially in Scotland, but often fairly mild further south, at times quite warm and humid.
